To all whom it may concern."

Be it known that I, DANIEL APPLEGATE, a

citizenof the United;States, residing at Lacarne, in the county of Qttawa and State of Ohio, have invented certain-new and useful Improvements in Gear Mechanism; and I, do hereby declarethe following to be a full, clear, and exact description of the invention, such aswwill enable others skilled in the art to whichit appertains to make and usethe same, reference being had to the 3C".

'cornpanyingdrawings, and to the letters-andk figures of reference marked :chereo'n, which fornra part of tlllS'SPGClflCtttlOl'Ly 1 This; invention relates tonew and useful improvements in geanmechanism for automobiles and comprises .a simple and efiicient apparatus of this natureso arranged that, by the manipulation of clutch throwing mechanism, a forward or reverse movement may be imparted to the clri-ving h y j the Vehicle. a v e p ,My invention comprisesvarious detailsiof construction: and combinations' and arrange Inen-ts of parts which will be hereinafter fully" described, shown in the accompanying drawings and then specifically defined in the 5 appended claims. v I 1 I illustratedmy invention in the accom-v panyingdrawingsin which:

Flgure 1 1s a top planv1ew. Flg. 2 1s a vertical sectionalvlew showing in elevation the clutch. 'Fig. 3 is anenlarged detailin elevation of'one of the sleeves and friction shoes mounted" thereon, and Fig. l is a sec-L tional viewlongitudinallythrough'the shaft upon which the clutch throwing lever is mounted. I T i 1 Reference now being-had to the details'of thedrawings' by letter, A and A designate 'two Qintermeshing wheels which are keyed to the shafts B and C respectively, which are journaled insuitable bearings in the frames'n v "A sprocket wheel E is fixed to the shaft 15 and to which power from an engine, not

showng is adapted tobe supplied.

' .Loosely mountedupon the shaft B is a gear iwheel-F and a-similar gear'wheel G is loosely mounted upon a shaft C.

' -Keyedto the shaft B is a sleeve J having GEAR, MECHANISM. y

tw-o fixed arms J projecting diametrically therefrom, and L. L designate frictionshoes, each pivoted at corresponding ends to the end of an arm.

Pivotally mounted upon each sleeve upon the pins 1 at points diametrically opposite are the resilient rods N, each bent to form a coil, one end of each being fastened to corre-' sponding ends of the shoes and forming means whereby, as said resilient rods turn upon their pivots, the shoes will be tilted upon their pivots and affording means whereby theffriction shoes may be thrown peripheral flange F of the wheel F.

A clutch collar M is splined to the shaft B andhas an annular groove M and to said splined sleevethe ends of said resilient rods are piv'otally connected and forming means whereby, forth upon the shaft B, the friction shoes may be moved accordingly toward or away fromthe flange F 1. V l

The shaft G has a sleeve C fixed thereto and has diametrically disposedarms (1 each pivotally connected toi'a corresponding end' of the shoes C which engage the inner-marginal edge of flange-G uponthe wheel G.,

I A sleeve Q, is splined to the shaft C and ber Panel which-is reinforced by the lateral braces T Said crankshaft is'journaled in T suitable hearings in the frame and has any suitable link androd connections extending to any suitable location wherebythe crank shaft may be rocked accordingly as it may be desired to cause the gear mechanlsm to drive in one direction, or in a reverse directlon'.

A shaft Sis journa'led insuitable bearings in the frame of the apparatus and to which a gear wheel S is fixedwhich is in mesh with the gear wheelF, and sprocket wheels W'are also fixed tothe shaft S and to which as the collar is moved back and Said clutch throwing member P,-

pi'votally connected to a laterally extending arm T projecting centrally from the meme sprocket chains are connected which in turn are adapted to pass over other sprocket wheels for driving the shaft of the vehicle.

The operation of my gear mechanism will be readily understood and is as follows:

\Vhen the engine is driving the gear wheels A to the right, the gear wheel A, which 1ntermeshes therewith, will be driven in the reverse direction by reason of the two wheels inter-meshing and the two shafts B and G willmove respectively. In the even of the clutchthrowing member being in a neutral position, which is parallel to the plane to which the two wheels A and A are located,

the two gear wheels F and G will remain idle. In the. event of it being desired to throw the clutch mechanism so that the sprocket wheels will rotate in a reverse direction to the rotary movement of the shaft will be thrown toward the gear wheel F and causing the shoes L to be thrown frictionally against the flange upon the face of the wheel F, thus causing the latter to rotate with the shaft B and impart a reverse ro- .tary movement to the shaft S, whichwill impart a similar movement to the sprocket wheels upon the shaft 5 and, through the medium ofthe'sprocket chain, propel the vehicle forward. A reverse rocking movement to the crank shaft willcause the resilient rods mounted upon the sleeve J to tilt upon their pivots and throw the shoes out of frictional contact with the flange upon the wheel F and theclutch sleeveupon the shaft C will be thrown toward the sprocket wheel G and cause the same to rotate with the shaft C, thus reversing the movement of the gear mechanism and causing a corresponding reverse movement to the vehicle. When the gear throwing shaft P is at a neutral position, which is in a plane parallel to the plane in which the wheels A and A are positioned, the two wheels F and G will be idle. i

By the provision of an apparatus embodying the features of my invention, it will be noted that, by the simple manipulation of the machanism connected with the lever, the gear mechanism may be caused to drive the wheels forward or reversely or the wheels thrown to positions of rest.
